Hey there. I hesitated to start yet another draining/winterization thread, but I can't find an answer to my exact question in any existing threads.
So, I've been working on winterizing my 2008 Four Winns H180 with a Volvo Penta 4.3 GL-J (manufactured March 2008) for the first time as we purchased it this past spring. Following the instructions in my owner's manual and the below thread, I pulled the blue plugs from either side of the engine block and from each exhaust manifold. A strong, steady flow of water drained from all four, just as I expected. I then pulled the hoses off the raw water pump, which also drained an expected amount of water. Then I pulled the large hose off the engine water circulation pump (at both the pump end and the thermostat housing end for good measure), again an expected amount of water drained. Lastly, I pulled the intake manifold drain plug (which, after fighting with the original one I'm replacing with a brass hex head plug per Don S' recommendation) and lowered the bow of the boat as far down as it would go and well...no water came out. OK, a very slight trickle amounting to no more than just a few drops of water did come out. But I expected more. I checked for obstructions by sticking my little finger in as far as it would go, and while there was a little corrosion obvious near the end of the threads, there was no blockage as far as I could tell.
I'll be keeping the boat in an attached garage over the winter, but it does occasionally get down to near 0* F outside here in Utah over the winter, so I want to make sure all water that will come out of the entire system is out. So, My question for any who have more experience than I do is this:
Should more water have come out of my intake manifold drain at the point I ended up removing it during the process or is it likely nothing to speak of came out because I did it last and the majority of the water in the intake manifold drained at the time I pulled the engine block plugs?
Thanks in advance!
